Bald spot on the chin: causes and next steps

The skin's appearance and the way the hairs have been lost help narrow the possibilities. A smooth, sharply outlined patch without scaling can occur with alopecia areata; redness, flakes, tenderness, pustules, or broken hairs point toward another process that needs examination.

Alopecia areata can present with one or more round, smooth patches in the beard while the skin surface looks otherwise normal. An inflamed fungal or bacterial problem is more likely to change the skin as well as the hair, although appearance alone cannot confirm the cause.

Close shaving, plucking, helmet straps, habitual rubbing, acne, and previous injury may also break hairs or affect follicles. Compare the patch with the opposite side and note whether it is widening, filling in, itchy, sore, or associated with hair loss on the scalp, eyebrows, or elsewhere.

Pause very close shaving and avoid picking, harsh scrubs, fragranced aftershave, or unprescribed steroid creams on the patch. Clean gently, use your own razor and towel, and take a clear photograph under similar lighting every few days so change is easier to judge.

A GP or dermatologist can inspect the hairs and skin and may examine other body areas or test material from the patch if infection is suspected. Treatment depends on the diagnosis; a hair transplant is not a first response to a new, unexplained beard patch.

Arrange a routine appointment if the patch persists, enlarges, returns, or new patches appear. Seek prompt care for spreading redness, marked swelling, pus, severe pain, fever, or a rapidly worsening rash, because these features can accompany an infection that needs targeted treatment.

Ask whether the pattern looks inflammatory, infectious, traumatic, or autoimmune; whether hair or skin testing would change management; which grooming products to stop; and what signs would mean returning sooner. Mention recent barber visits, new medicines, skin products, and similar hair loss in other areas.
